US Patent 7870294 Method and apparatus for providing policy-based document control

A method and apparatus for providing policy-based document control includes a client node, a collection agent, a policy engine, and a transformation server. The client node requests access to a resource. The collection agent gathers information about the client node. The policy engine receives the gathered information and makes an access control decision based on the received information. The transformation server transforms the contents of the file from a native format to a second format and presents the transformed contents of the file to the client node.
